ABSTRACT
The genus Veillonella encompasses multiple species of gramnegative, anaerobic cocci belonging taxonomically to the family Veillonellaceae, order Clostridiales, class Clostridia, phylum Firmicutes. At the present, a total of 11 species are recognized within the genus, including, Veillonella atypica, Veillonella caviae, Veillonella criceti, Veillonella denticariosi, Veillonella dispar, Veillonella magna, Veillonella montpellierensis, Veillonella parvula, Veillonella ratti, Veillonella rodentium, and Veillonella rogosae.1-5
Members of the genus Veillonella (Veillonella, named after Adrien Veillon) lack ³agella, spores, and capsule. Apart from V. criceti, Veillonella species do not ferment carbohydrates (to lactic acid) or amino acids, and they rely on the fermentation of lactate, pyruvate, malate, fumarate, and/or oxaloacetate as a source of carbon and energy.6
